As influenced by ground conditions, weather: wind, rain, etc
Your assessment of your own grassland management/quality of grass currently available
Daily grazing area is calculated using pre and post grazing cover and estimated total grass DMI. However in poorer conditions/lower quality swards, cows will eat less, but will not necessarily need less area, as some grass will not be utilised, due to tramping etc.
Assumes all cows eat same amount of grass, irrespective of milk yield or level of concentrate fed. Maximum parlour feed levels should not exceed 10 - 12 kg/day.
Assumes all heifers eat same amount of grass(20% less than cows), irrespective of milk yield or level of concentrate fed. Maximum parlour feed levels should not exceed 8 - 10 kg/day.
The effect of buffer feeding on grass intake is influenced by many factors such as; grass availability, grass quality and grazing conditions. With good quality swards and good grazing conditions, buffer feeding may not improve dry matter intake.
